Types of Software

Study Notes

Software refers to a set of instructions or programs that tell a computer what to do.
It is a collection of data, instructions, and algorithms that tell a computer how to perform a specific task.

System Software: manages and controls computer hardware components and provides a platform for running application software. Examples: operating systems, device drivers, and utilities.
Application Software: performs specific tasks or provides services to users. Examples: word processors, web browsers, and games.
Programming Languages: used to write software programs. Examples: Java, Python, and C++.

Intangibility: software is an intangible product, meaning it can't be physically touched.
Customizability: software can be modified or customized to meet specific user needs.
Reusability: software can be reused in different applications and environments.

SDLC (Software Development Life Cycle): a process used to design, develop, test, and deliver software. Phases: planning, analysis, design, implementation, testing, and maintenance.
Programming Paradigms: approaches to writing software code, including:
- Object-Oriented Programming (OOP): organizes code using objects and classes.
- Procedural Programming: uses procedures or functions to perform tasks.
- Functional Programming: uses pure functions to perform tasks.

Proprietary Software: owned by an individual or organization, with restrictions on use and modification.
Open-Source Software: freely available, with users allowed to modify and distribute the software.
Free Software: similar to open-source software, but with additional freedoms for users.

Productivity Software: helps users perform tasks, such as Microsoft Office.
Graphics and Design Software: used for creating visual content, such as Adobe Photoshop.
Gaming Software: provides entertainment, such as video games.
Enterprise Software: supports business operations, such as customer relationship management (CRM) systems.
